UNITESTATES 1'0 all whom it may concern:

Be it known that We, OHARLns HOLTMANN, WILLIAM H. LINDEWIRTH,andJ OHN SoHUNK,

citizens of the United States of America, residing at Pittsburg, in the county of AlleghenyandSlate ofPennsylvania,haveinvent edcertain new and useful Improvements in Foot Guards for Rai1way Frogs', of which the a following is a specification; reference being had therein to the accompanying drawings.

This invention relates to certain new and I useful improvements in foot-guards for railwayirogs; and the invention has for its object to construct a guard adjustable so as to I5 fit any difierent-sized frog.

The invention has for its further object to construct a device of this kind with means for readily adjusting the 83.1116, soles to fit the frog in which theguard is to beplaoed.

. 2c Brieflydescribed, the invention comprises a guard embodying two sections which partly overlap and also providing means whereby the sections are spread apart in order to conform" the same tothe frog in which they are to beemployed.

I In describing the invention in detail reference is had to the accompanying drawings, formingapart of this specificatiomand where I in like numerals of reference indicate like f 0 parts throughou tthe several views,in which-- Figure l is a detail perspective view of our 1 improved foot-guard in position in the frog. Fig. 2 is a horizontal sectional view of the frog and guard with the latter in position. 5 Fig. 3 is a transverse vertical sectional view ofthe frog and guard. Fig. 4 is a longitudinal sectional viewthereof. Fig. 5 is a like view of a modifiedforrn of construction. Fig. 6 isa like view of another modifiedform of construction. Fig. 7 is atop plan view showrs or sections "one of which overlaps the 4 other and whichsections or members when joined together-are practically wedge-shaped in formgsoas to conform to the shape ofthe frog. Each of the sections is preferably formed of. comparatively thin plate or bar mettththesection or member lroverlapping.

:SBEGIFICATION forming rt f. Letters Patent No. 723,156, dated March 17, 1903 I Applicationfiledilannary5,1963 $erialNo.137,895. (no modelii the upper plate of the section ,or member 2, and each section or member tapers to a point, the sections or members beingjoined together near the small end by the bolt and nut 3 passing through the topplates'of the members. Each sectionor member is shouldered 0E, as at 4, wherebyto form a side ridge 5, which is adapted to fit against the web of the rails of the frog between the tread and the base of said rails. Each section or member may be 6o provided with front end walls 6, as seen in Fig. 2, and they are also provided with rear end walls 7, which latter end Walls are provided with registering slots 8 to receive the shank of the adjusting-screw 9. The screw portion of this screw engages in the spreader-bar 10, which is shaped at its ends to conform to the inclined or tapered portionof the inner walls of the guard. This adjusting-screw carries a nut 11 and the head 12, the shank portion 14 between the nut 11 and head 12 operating in the slots 8 and also engaging through the upwardly-extending member 14 of the angleplate 16, which latter is provided with apertures whereby the screw may be spiked to the cross-ties, as seenLin Fig. l of the drawings. The adjusting-screw being held in the upwardly-extending member of the angle-plate it will be observed that the turning of the screw will force the spreader-bar inwardly or draw the same outwardly, according to the direction in which the screw is turning, and consequently spread the sectionsor member 'or permit the same to be drawn closer together, whereby to accommodate the width of the 8 frog upon which the guard is being used.

In Fig. 5 we show the same form of guard member, the only difference being in this construction that the angleplate 17 extends inwardly for some distance and carries an 0 upwardly-extending member 18, which'is in close juxtaposition to the spreaderrbar 10.

In Fig. 6we show the same construction of guard with the angle-plate19,-.the up- Wardly-extending member ZO of which is adapted to be placed over the head of the adjusting-screw, whereby to prevent actuating the latter without removal of the securing-plate. The securing-platein both the constructions shown in Figs. 5 and 6 is adapted to be spiked down to the cross-ties, as shown in Fig. 1 of the drawings.

It is to be noted that the spreader-bar acts also as a brace for the 'two members comprising the guard, as the ends of the spreaderbar are always in engagement with the inner face of the side walls after the members have been adjusted.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention what we claim as new, and desire to secure by Letters Patent, is-- 1. A guard for railway-frogs comprising two substantially wedge shaped members overlapping each other and each of which is shouldered off along the side edge to form a ledge to engage withthe web of the rails, an adjusting-screw, and a spreader-bar on said screw, as and for the purpose described.

2. In a guard for railway-frogs, two overlapping substantially wedge-shaped members having slotted rear end walls, an adjustingscrew mounted in said slotted end walls,-and

a spreader-bar engaged by said adjustingscrew,v substantially as described.

3. A guard for railway-tracks comprising two overlapping members substantially wedge-shaped and having shouldered-off side edges, slotted end Walls on said members, a securing-plate, an adjusting-screw mounted in the slotted end walls and securing-plate, and a spreader-bar engaged by said adjustingscrew, substantially as described.

4. In a guard for railway-frogs, two overlapping members substantially wedgeshaped in form, an adjusting-screw mounted in the rear end walls of saidmembers,and aspreaderbar engaged by said adjusting-screw and acting as a brace for the members, substantially as described.

In testimony whereof we affix our signatures in the presence of two witnesses.
